Abstract
Изобретение относитс к арматуростро- ению и может быть использовано в испытательных системах высокого давлени . Цель изобретени - повышение надежности работы за счет упрощени конструкции. Толкатель 9 выдвигаетс до соприкосновени с клапаном 4 и, преодолева усилие пружины 6, перемещает клапан 4 до упора его в клапан 5. При этом тыльные стороны клапанов 4 и 5 смыкаютс , а рабоча часть клапана 5 прижимаетс к рабочей кромке гильзы 3. 3 этом режиме полость в отсекаетс , и рабоча жидкость не поступает ни в полость нагнетани г ни в полость сброса д. Толкатель 9 выдвинут в крайнее верхнее положение. Подведенна к по/юсти в жидкость своим ачлением поднимает клапан Ч, преодолева усилие пружины 6. Жидкость проходит в кольцевую щель между клапаном 5 и пользой 3 а затем через отверстие а и через полость г к потребителю. 4 илThe invention relates to a valve and can be used in high pressure testing systems. The purpose of the invention is to increase reliability by simplifying the design. The pusher 9 extends until it touches the valve 4 and, overcoming the force of the spring 6, moves the valve 4 until it stops in the valve 5. The rear sides of the valves 4 and 5 are closed and the working part of the valve 5 is pressed against the working edge of the sleeve 3. 3 this mode the cavity is cut off, and the working fluid does not flow either into the discharge cavity or into the discharge cavity. The pusher 9 is extended to its extreme upper position. The supply to the fluid in its position raises the valve H, overcoming the force of the spring 6. The fluid passes into the annular gap between valve 5 and use 3 and then through the opening a and through the cavity r to the consumer. 4 yl
